Seeing the summary route generated on R3 , AS_PATH inherits the detailed AS_PATH and presents it in the form of {100 , 200} , which can prevent the loop from happening, and will not cause hidden dangers due to the loss of the AS_PATH of the detailed route. . Note that the AS_PATH type in {} is AS_SET and is an unordered list of ASs . New and R3 of BGP connections, and is using the AS201 and R3 ( AS300 ) established EBGP neighbor relationship. Underline, matching any separator such as ^ , $ , space, tab , comma, { , } Neighbor VLAN works on the second layer of the OSI reference model R1 and R2 run RIP ; R2 and R3 establish OSPF neighbor relationships. In the initialization case, there are four entries in the routing table of R2 , as shown in the figure above, and there are only two entries in the routing table of R1 ,ccnp switch certification guide pdf, that is, two direct links. So now, we do the re-release action on R2 , and redistribute the OSPF route to RIP , then the configuration is as follows: Weight MAC address Then, R3 deploys the two-way re-release, so the process 2 route is injected into process 1 , then the route of the A network segment will be injected back into process 1 , so that the priority of O is greater than OE , so R1 and R2 directly ignore this. Strip routing. Will not cause other effects. The interface will only receive updates, no updates will be sent. Passive interface Ip dhcp pool vlan10 network 192.168.10.0 /24 Weight AS_PATH is a recognized attribute that describes the sequence of AS numbers that will pass through to the destination network . The most important role is anti-ring. If the BGP speaker finds that its AS number is located on the route received from the external peer, the route is ignored. 5 Y The TCN BPDU contains three fields, which are identical to the first three fields except the type field of the configuration BPDU . 100 i \ Tags 3.0.0.0/24 is subnetted, 1 subnets Aging Type : Absolute SecureStatic Address Aging : Disabled 100 Static Routing DAI working mechanism Multiplication character RSTP port status After aggregate-address 192.168.0.0 255.255.0.0 , R1 can learn summary routing and 2.0 Then, first R2's own routing table will change, 3.0 routing is filtered out, and R3 is the downstream RIP router, 3.0 can not learn. The configuration commands are as follows: In the above configuration, the maximum number of secure addresses is set to 3 , and then a secure address is manually configured. Then there are two remaining , and the switch can construct a secure address through dynamic learning. ... Switch(config)# spanning-tree [ vlan vlan-id ] hello-time sec Switch(config)# spanning-tree [ vlan vlan-id ] forward-time sec Switch(config)# spanning-tree [ vlan vlan-id ] Max-age sec 1000 Neighbor 10.1.23.2 route-map setCommu in To be a whole, that is, to see the cluster as a whole. Look at the top of topology, AS300 has a subnet 172.16.1.0/24 , AS400 has routes 172.16.2.0/24 . Then in each sequence, we can define two elements for policy deployment: matching conditions, performing actions . You can define multiple conditions, and when the conditions are matched, they will perform the relevant actions specified by the set . Slightly mention here, the set statement is not necessary, for example, if the route-map is only to match the traffic of interest, then there may be only a match statement and no set statement.
